I use an Odyssey Neo G7 43" monitor and its great for my Xbox Series X also.
Best Buy is selling them cheap right now. ($499 as of writing this) <---
Awesome price
I think the low price is because nobody wants a huge monitor for their computer. The 32" version is more expensive. I solved getting
sea sickness of huge monitor by scooting my monitor to the very back of my table. Table width is 35" and the back of the base is almost touching it. Also setting Windows monitor scaling to 200%
